Found a Python 2 script on the Stack Exchange, and converted it into a python 3 script. Brought in the parent and child versions into a project as separate database connections, so I could have two different paths for the parent and child version.
import arcpy
import os
inputDataset = r"C:\Users\vazquel\OneDrive\Documents\LocalWorkspace\Parent.gdb\ParentVersion"
targetDataset = r"C:\Users\vazquel\OneDrive\Documents\LocalWorkspace\Child.gdb\ChildVersion"
outputFolder = r"C:\Users\vazquel\Desktop\LocalWorkspace\ComparisonReports"
outputName = "Comparison_Report_1"
inputDict = {}
changes = []
#GET FIELDS
arcpy.AddMessage("Getting Fields\n")
fields = ["OID@", "Shape@JSON"]
fieldList = arcpy.ListFields(targetDataset)
for field in fieldList:
if field.name not in ("OBJECTID", "SHAPE", "Shape_Length", "Shape_Area", "RuleID", "Override"):
fields.append(field.name)
#SEARCH INPUT DATASET, ADD DATA TO DICTIONARY
arcpy.AddMessage("Searching Input Dataset\n")
with arcpy.da.SearchCursor(inputDataset, fields) as inputRows:
for inputRow in inputRows:
oid = inputRow[0]
geom = inputRow[1]
attrs = {"Geometry":geom}
for i in range(len(fields)):
if i > 1:
field = str(fields[i])
attrs[field] = inputRow[i]
inputDict[oid] = attrs
#SEARCH TARGET DATASET AND COMPARE TO DICTIONARY DATA
arcpy.AddMessage("Searching Target Dataset\n")
with arcpy.da.SearchCursor(targetDataset, fields) as targetRows:
for targetRow in targetRows:
# If no match in dictionary, it's a delete
oid = targetRow[0]
if oid not in inputDict.keys():
changes.append([oid, "Delete", "N/A", "N/A", "N/A"])
else:
# If geometries don't match, it's a geometry update
geom = targetRow[1]
if geom != inputDict[oid]["Geometry"]:
changes.append([oid, "Geometry Update", "N/A", "N/A", "N/A"])
# If attribute values don't match, it's an attribute update
for j in range(len(fields)):
if j > 1:
field = str(fields[j])
value = targetRow[j]
if value != inputDict[oid][field]:
changes.append([oid, "Attribute Update", field, value, inputDict[oid][field]])
# If there was a match, remove item from dictionary
del inputDict[oid]
#Anything left in the dictionary is an added feature
for oid in inputDict.keys():
changes.append([oid, "Add", "N/A", "N/A", "N/A"])
#Write Output Change File
arcpy.AddMessage("Writing Output File\n")
outputFile = open(outputFolder + os.sep + outputName + ".csv", "w")
outputFile.write("OID,CHANGETYPE,FIELD,INPUTVALUE,TARGETVALUE\n")
for change in changes:
line = ""
for item in change:
line += str(item)
line += ","
line = line[:-1]
line += "\n"
outputFile.write(line)
arcpy.AddMessage("\n\nAll Done!\n\n")
outputFile.close()
